Abstract:
An electrical connection line (L) for an electrical unit of a motor vehicle, which electrical connection line serves to electrically connect the unit to an electrical power source which is arranged in the motor vehicle and/or to another electrical unit. The connection line (L) is designed as a three-phase line with three insulated electrical conductors (1, 2, 3), of which each has an electrical individual sheath (5) which is in contact with its insulation means (4) and is closed all the way around. An electrical outer sheath (7) which surrounds the three sheathed conductors (1, 2, 3) and is closed all the way around is also provided and a coupling element which is equipped with electrical contacts which are insulated from one another is fitted at least to one end of the connection line (L) in a moisture-tight manner, and the electrical conductors (1, 2, 3), their individual sheaths (5) and the outer sheath (7) are electrically conductively connected to the contacts of the said coupling element.
Abstract:
The invention pertains to a device for acquiring signals from sensors (1) installed in a motor vehicle, where at least two sensors, which are connected by electrical conductors to a source of electrical voltage (2) and to an evaluation unit (3), are mounted in different positions in the vehicle. To simplify the installation of the device, the sensors (1) are attached a certain distance apart to a common ribbon cable (4) with parallel electrical conductors, which cable has at least one conductor which can be connected to the voltage source (2) to supply power to the sensors (1) and several signal conductors, which can be connected to the evaluation unit (3) and possibly also to the voltage source (2), the number of which corresponds to the number of sensors to be connected. All of the sensors (1) are connected to the power-supply conductor, and each one is connected individually to one of the signal conductors.

Abstract:
Dyes are transferred from a substrate to an acceptor by sublimation or vaporization of the dye by means of a thermal printing head by using a substrate on which there is situated cationic dyes having a cyanine chromophore and one or more N-H groups which are part of the cyanine chromophore, in their electrically neutral form as the result of deprotonation at the N-H group and transferring these deprotonated dyes to a coated paper.
